Phase I of this effort involves the creation of a comprehensive end-to-end model of a novel holographic polarimeter.The polarimeter that can be constructed based on our model will be able to determine the full polarization properties (Mueller matrix elements) of scattering, reflecting and absorbing media as a function of the materials depth.Unlike previous attempts, this system will be a real-time ...

The advancement of flight vehicles, including hypersonic vehicles, requires increased performance from RF shielding material capable of withstanding the dynamic and thermal loads of the vehicle while maintaining RF performance.Efforts conducted as a response to this program will develop and characterize material for use as radomes and conformal apertures of flight vehicles and other extreme enviro ...

Nutronics, Inc. and Montana State University propose to develop an approach for non-linear control of hysteresis and incorporate (if necessary) integrated Multi-Input-Multi-Output real time control with this capability.Our control systems already include a proven high speed real time control approach to determine the optimal set of actuator commands that satisfy inter-actuator stroke limitations.O ...

Adaptive optics (AO) system performance is hindered by the mechanical limits of the deformable mirror (DM), namely stroke limits, interactuator stroke limits, and mechanical resonance.The nature of the multi-in multi-out (MIMO) control system does not lend itself well to notch filters to combat the mechanical resonances, and the stroke limits introduce non-linearities to the system.The traditional ...

This SBIR project will develop and demonstrate efficient electron emitter based on carbon nanotubecopper (CNT-Cu) composite for passive discharging of spacecraft in plasma environment. A spacecraft moving through harsh plasma environment collects electrons, which leads to the spacecraft charging up to several kilovolts. High voltage between different parts of the spacecraft can ignite arcing, whic ...

As the frequency spectrum gets more congested, chances of harmful interference become an issue.Enemies can intentionally jam or desensitize receivers in battle critical electronic warfare systems.A tunable band stop filter with wide tuning range is required to instantaneously adapt and reject such malicious interference.Nuvotronics will collaborate with UC Davis in this STTR to bring MEMS based tu ...

Traumatic brain injury is a common problem in both the military and civilian communities, but current treatment protocols are focused on managing symptoms and fail to prevent significant long-term repercussions. In the proposed program, Luna will demonstrate the feasibility of a liposome-based therapeutic delivery system capable of delivering hydrophilic and hydrophobic therapeutics to the traumat ...

Kyma Technologies, the leading domestic supplier of crystalline III-N substrate materials, is teamed with leading AlGaN materials & device experts at Sandia National Laboratories (SNL) to develop high-quality n-type conductive 2-inch diameter epi-ready free-standing AlGaN substrates in support of next generation AlGaN devices with applications in ultraviolet optoelectronics, power electronics, and ...

For prediction of hypersonic aerothermodynamics, knowledge of the relevant disturbance levels is required to determine transition locations in flight at the altitudes of interest. Tao Systems and University of Maryland (UMD) propose to develop a flight platform and measurement system capable of acquiring pressure, temperature, density, velocity fluctuations, and particulates using a miniaturized, ...

This Phase-II STTR research effort is designed to forward the engineering investigation of the dynamics and control of turbulent combustion in high-pressure combustion systems by developing a set of game-changing nonlinear analysis tools that can significantly improve the post-processing speed and intelligent data mining of large numerical or experimental data sets. Moreover, a system based on non ...
